The population of Dublin increased 4.5% from 2017 to 2018, making it one of the fastest-growing cities in the country, according to data released Thursday by the Census Bureau.

Dublin, with an estimated population just shy of 65,000 last year, was the only California municipality to crack the top 15 U.S. cities for resident population change over that period. It’s held the designation on and off in the last decade.

“I don’t think it’s any real surprise to anyone,” said City Councilman Shawn Kumagai. “It’s definitely changed. The face of Dublin has changed as we’ve executed on our buildout.”

The city’s growth vastly outpaced its Tri-Valley neighbors. Livermore’s population went up about 200 residents, or 0.3%, and Pleasanton had a net loss of about 400 residents, a decline of 0.4%.

Dublin has done a better job than most Bay Area cities in meeting the housing demanded by new residents, going above the “regional housing need allocation” numbers that state and local officials set. Of the new units approved from 2015 to 2017, however, almost all of them were “above moderate” — meaning only those making 120% of area median income could afford the homes. The city approved just a handful of units for families with very low, low and moderate incomes.

“It’s a problem that people are being priced out of Dublin,” Kumagai said. “But Dublin is still one of the more affordable communities in the Bay Area. It’s geographically ideal. We have two BART stations, and we have additional developments in the works near our transit centers.”

The Tri-Valley saw jobs grow 35% from 2006 to 2016, outpacing San Francisco and Silicon Valley. The cities of Danville, Dublin, Livermore, Pleasanton and San Ramon benefited from the presence of two federal laboratories, along with less expensive housing and office space compared with the Bay Area’s urban centers, according to a report from the business-backed Bay Area Council Economic Institute and Innovation Tri-Valley Leadership Group.

San Francisco added about 4,000 residents from 2017 to 2018, a change of 0.5%. Oakland increased its population 1.2% with the addition of 5,000 new residents. San Jose, which continues to have a larger population than any other Bay Area city, lost about 2,000 residents, a decline of 0.2%.

In terms of pure numeric gain, San Diego added more residents — some 12,000 — than any California city from 2017 to 2018. It was the only one to crack the top 15 nationwide. Los Angeles came in second for cities in the state, adding about 8,000 residents.
